Safeguarding confidential information during a screen share session

ABSTRACT

A method for safeguarding confidential information during a screen share between two computing devices each having a screen. The method includes receiving, from a first computer, a request to share content of one or more applications displayable on a screen of a second computer. The method further includes summarizing the content to be displayed by the one or more applications, and transmitting, by the first computer, the summarized content to be shared by the one or more applications with the second computer. In exemplary embodiments, the summarized content may be password protected. The method may further include prompting, by the second computer, a password entry and displaying, by the second computer, the summarized content based on a password match.

BACKGROUND

Embodiments of the present invention relate generally to the field of computing and more particularly to data processing and protecting confidential information during a screen sharing session between multiple users.

Screen sharing is a common way for two or more users to work collaboratively with each other or to communicate interactively. The availability of instant messenger chat programs and web-conferencing, together with document sharing, has led to closer working relationships between employees, even if those employees may be sitting in offices on opposite ends of the world. In many work environments, two or more employees currently have the option to share a computer screen with another member of their team, thereby fostering a closer working relationship as well as increasing the chances of revealing confidential documents, emails, or other private information that may be open during a screen sharing session.

Oftentimes, a user may not pay close attention to content they are sharing, or perhaps not even realize that confidential information is contained within the content they are sharing. This may be due to a user being in a rush, or simply being careless.

Currently, there is no mechanism to automatically hide confidential or private information that a user is sharing during a screen sharing session.

SUMMARY

DETAILED DESCRIPTION

Currently, there is existing software such as IBM SameTime® (SameTime is a registered trademark of IBM Corporation) meeting room that allows the user to share either their whole screen or just a file. Furthermore, there are additional precautions that must be considered when a user shares either their screen or a file.

The present invention can intelligently share a user screen, or file, with message composition styles to prevent the user from sharing private or confidential information by accident. For example, sometimes a user may not intend to have certain private applications open on their desktop during a screen share, or send a particular file to a recipient. Other times, a recipient may have other people in the room who are not intended recipients of the shared information.

Some of the message composition style techniques disclosed by the present invention may include only sharing a few keywords in the screen share session, rather than a full message. In this instance, a sender can choose to expand the full message through additional menu selections or a mouse click. This safety measure provides a second look for the sender in order to ensure that the sent message, or file, is the correct message or file for the intended recipient.

Another message composition style technique disclosed by the present invention may include only displaying a code name that can be understood between the sender and the receiver, or popping up a small avatar to ask the receiver whether it is OK to currently share the screen.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the attached drawings.

The present invention is not limited to the exemplary embodiments below, but may be implemented with various modifications within the scope of the present invention. In addition, the drawings used herein are for purposes of illustration, and may not show actual dimensions.

FIG. 1 illustrates a screen sharing computing environment 100, in accordance with an embodiment of the present invention. Computing environment 100 includes first computing device 110, second computing device 130, and database server 140 all connected via network 102. The setup in FIG. 1 represents an example embodiment configuration for the present invention, and is not limited to the depicted setup in order to derive benefit from the present invention.

In the example embodiment, first computing device 110 contains user interface 112, application 114 a, and screen sharing protection program 120. In various embodiments, first computing device 110 may be a laptop computer, tablet computer, netbook computer, personal computer (PC), a desktop computer, a personal digital assistant (PDA), a smart phone, or any programmable electronic device capable of communicating with second computing device 130 and database server 140 via network 102. First computing device 110 may include internal and external hardware components, as depicted and described in further detail below with reference to FIG. 5. In other embodiments, first computing device 110 may be implemented in a cloud computing environment, as described in relation to FIGS. 6 and 7, herein. First computing device 110 may also have wireless connectivity capabilities allowing it to communicate with second computing device 130 and database server 140, as well as other computers or servers over network 102.

In an exemplary embodiment, user interface 112 may be a computer program that allows a user to interact with first computing device 110 and other connected devices via network 102. For example, user interface 112 may be a graphical user interface (GUI). In addition to comprising a computer program, user interface 112 may be connectively coupled to hardware components, such as those depicted in FIG. 5, for receiving user input. In an example embodiment, user interface 112 is a web browser, however in other embodiments user interface 112 may be a different program capable of receiving user interaction and communicating with other devices.

In an exemplary embodiment, application 114 a may be a computer program, on first computing device 110, that is capable of communicating with another computer, such as second computing device 130. In an exemplary embodiment, application 114 may be an instant messenger service on first computing device 110 that is capable of sharing a computer screen with other users, receiving and/or sending data files, instant messaging, web-conferencing with a group of one or more users, or sharing information on first computing device 110 with second computing device 130 via any other known method to one of ordinary skill in the art. In exemplary embodiments, data files may include, but are not limited to, word processing files, video files, audio files, graphics files, and so forth.

In an exemplary embodiment, application 114 is depicted in FIG. 1 as application 114 a on first computing device 110, and as application 114 b on second computing device 130 thereby illustrating that application 114 is the same on both first computing device 110 and computing device 130. For example, a first user, on a first computing device 110, may utilize the functionality (e.g. screen share, file transfer) of an instant messaging application only if a second user, on a second computing device 130 also has the same instant messaging application.

In an exemplary embodiment, screen sharing protection program 120 contains instruction sets, executable by a processor, which may be described using a set of functional modules. The functional modules of screen sharing protection program 120 include data analysis module 122, data summarization module 124, and information delivery module 126.

With continued reference to FIG. 1, second computing device 130 contains user interface 132 and application 114 b may be a laptop computer, tablet computer, netbook computer, personal computer (PC), a desktop computer, a personal digital assistant (PDA), a smart phone, or any programmable electronic device capable of communicating with first computing device 110 and database server 140 via network 102. While second computing device 130 is shown as a single device, in other embodiments, second computing device 130 may be comprised of a cluster or plurality of computing devices, working together or working separately. Second computing device 130 may be implemented in a cloud computing environment, as described in relation to FIGS. 6 and 7, herein. Second computing device 130 may also have wireless connectivity capabilities allowing it to communicate with first computing device 110 and database server 140, as well as other computers or servers over network 102.

In an exemplary embodiment, user interface 132 may be a computer program that allows a user to interact with second computing device 130 and other connected devices via network 102. For example, user interface 132 may be a graphical user interface (GUI). In addition to comprising a computer program, user interface 132 may be connectively coupled to hardware components, such as those depicted in FIG. 5, for receiving user input. In an example embodiment, user interface 132 is a web browser, however in other embodiments user interface 132 may be a different program capable of receiving user interaction and communicating with other devices.

With continued reference to FIG. 1, database server 140 includes application content sharing history database 142 and may be a laptop computer, tablet computer, netbook computer, personal computer (PC), a desktop computer, a personal digital assistant (PDA), a smart phone, a server, or any programmable electronic device capable of communicating with first computing device 110 and second computing device 130 via network 102. While database server 140 is shown as a single device, in other embodiments, database server 140 may be comprised of a cluster or plurality of computing devices, working together or working separately.

In an exemplary embodiment, application content sharing history database 142 may store an application type, a shared data file type, sharing frequency, communication history, and so forth which may be depicted as a data model. For example, the data model may identify the content of the shared data file (e.g. whether the application content is text, graphics, images, or video), whether it is possible to have a summarized or shortened message (e.g. 1 for “yes”, 0 for “no”), recipient, and frequency. As such, a data model stored in application content sharing history database 142 may appear as <JPEG, 1, user3, 5>.

In further embodiments, application content sharing history database 142 may store an application sharing history organized by recipient, type of file, and screen sharing protection in place to protect private or confidential information for a particular file or application. In alternative embodiments, application content sharing history database 142 may be organized in any fashion deemed most useful for the invention to be utilized.

In various embodiments, application content sharing history database 142 may be stored on first computing device 110 as a separate database.

FIG. 2 is a flowchart illustrating the operation of screen sharing protection program 120, in accordance with an embodiment of the present invention.

Referring now to FIGS. 1 and 2, screen sharing protection program 120 may detect a screen share of one or more applications having content and safeguard confidential information from being inadvertently revealed during a screen share.

With continued reference to FIGS. 1 and 2, data analysis module 122 includes a set of programming instructions in screen sharing protection program 120. The set of programming instructions is executable by a processor. Data analysis module 122 receives, from a first computing device 110, a request to share content of one or more applications displayable on a screen of a second computing device 130 (step 202). For example, one or more applications may be a text document, a power-point presentation, a spreadsheet, an image, or any other type of software medium that may be shared, and displayed, electronically with another computing device.

In an exemplary embodiment, data analysis module 122 analyzes which applications, or which portion of the computer screen of first computing device 110, tend to be shared the most during a screen sharing session with second computing device 130. Data analysis module 122 may detect the nature of the one or more applications to be shared during a screen sharing session with second computing device 130, for example the application may be an e-mail client, an instant messaging client, a word processing client, or a software development integrated development environment (IDE) client.

In exemplary embodiments, data analysis module 122 determines which of the one or more applications contain either a lot of text or graphics, or essentially a lot of content. A lot of content within an application may increase the chance of a user sharing information that is confidential. In exemplary embodiments, data analysis module 122 may determine a lot of content within an application by detecting a word count, a file size, and/or analyzing metadata of an application.

Data analysis module 122, in exemplary embodiments, may determine which application is suitable for shortening (i.e. summarizing) text content or graphical content in an application. For example, an e-mail client's text may be shortened through enabling technology, while source code in an IDE may be more difficult to be summarized.

With continued reference to FIGS. 1 and 2, data summarization module 124 includes a set of programming instructions in screen sharing protection program 120. The set of programming instructions is executable by a processor. Data summarization module 124 summarizes the content to be displayed by the one or more applications (step 204). Summarization of content within an application may simply be taking the subject line of an e-mail, for example, and displaying only that portion of the e-mail. In other embodiments, summarization may include performing a natural language text analysis of a text document and displaying a span of the text that includes a general concept, or idea, without including any sensitive or confidential information (e.g. names, numbers, locations), such as specific information about the general concept. In yet other embodiments, summarization of an image or video may include performing image analysis techniques to display only a generic thumbnail of a portion of the image, or video.

In exemplary embodiments, data summarization module 124 may determine that the received content contained within one or more applications may contain confidential content. As such, data summarization module 124 may be capable of summarizing the content of the one or more applications containing confidential content. Applications that may contain confidential content may include a web browser, an instant messaging application, a work/private e-mail account, just to name a few. These applications contain potentially confidential content, since, if left open a user's desktop, may disclose confidential information on a screen share with a second computing device 130. Examples of confidential content within these applications may include a business spreadsheet, a private website, an e-mail discussing confidential work-related matters, a private instant message chat discussing a confidential project, tax information, medical information, and so forth.

In another exemplary embodiment, data summarization module 124 may be capable of allowing the user who shares the content of one or more applications displayed on their computer screen (i.e. of first computing device 110) to further highlight the currently summarized content (e.g. text, graphics, video), with recipients of the content of the one or more applications displayed on the screen of second computing device 130, by selecting a context menu to expand the summarized content to full content as needed, on the fly.

FIG. 3 depicts a shared computer screen containing summarized content of a slide in a power-point presentation, in accordance with an embodiment of the present invention.

With reference to FIGS. 1-3, second computing device 130 may receive the summarized content shared by the one or more applications and display the summarized content on the computer screen of second computing device 130.

In alternative embodiments, and with continued reference to FIGS. 1-3, a user on computing device 110 may be sharing the content of one or more applications displayed on her computer screen, for example a power-point presentation, in a web conference with multiple users using multiple computing devices, including second computing device 130, at once. Some of the users may not be privy to viewing some of the information presented. In this scenario, data summarization module 124 may only display a summarized content of the slide, for example “Software Functional Specification”, rather than the entire power-point slide. In this scenario, the users with clearance to view the full slide may need to input a password to unlock the slide contents. Alternatively, the user sharing the screen may have the option to lock/unlock the summarized content for a pre-configured list of recipients of the screen share.

With continued reference to FIGS. 1-3, in exemplary embodiments, the summarized content of an application may be password protected, wherein data summarization module 124 prompts a request to view the summarized content shared by the one or more applications. Second computing device 130 may display the summarized content based on a password match entered by a user of second computing device 130.

In another exemplary embodiment, the user who shares content of one or more applications displayed on the computer screen may click on the lock/unlock button to reveal the password protected (i.e. locked) summarized content (e.g. text, graphics, video) and select a context menu to expand the content to full content as needed on the fly. This mechanism prevents unwanted disclosure of confidential or private information and provides the user, who is screen sharing the displayed content, with additional control over the content on the screen share.

In an exemplary embodiment, data summarization module 124 may provide a user of the first computing device 110 with an option to select a context menu to expand the summarized content to full content, as needed, or to contract the full content back to the summarized content, as needed.

With reference to an illustrative example, user A may be engaged in a screen sharing session with user B. Data summarization module 124 may detect that user A has unintended open documents, or applications, displayed on his shared screen, and summarize the content within those documents/applications. Furthermore, data summarization module 124 may summarize the content of an application that user A intended to share with user B. This feature may prevent unintended disclosure of confidential, or private, content based on user A's oversight, or carelessness. In this embodiment, user A maintains full control over the displayed content on her screen by controlling the expanding, or contracting, of the summarized content of shared documents/applications by the click of a mouse, for example. In exemplary embodiments, user A may have the option to turn on/off the data summarization feature at any time.

FIG. 4 depicts a shared computer screen containing full content of a slide in a power-point presentation, in accordance with an embodiment of the present invention.

With reference to FIGS. 1-4, in alternative embodiments, data summarization module 124 may share the summarized content of first computing device 110 with second computing device 130, and require a password match, entered by a user of the second computing device 130, to reveal, or share, the content of the one or more shared applications. FIG. 4 depicts a screen share of an application, from computing device 110, to a user of second computing device 130 who successfully enters a password to access the full content of the power-point slide.

In alternative embodiments, data summarization module 124 may determine, by natural language processing, that the received content of the one or more applications contain confidential content, wherein the confidential content comprises any one of a personal name, address, bank information, telephone number, date of birth, and social security number, or any combination thereof, and summarizes the confidential content. For example, natural language processing techniques, within data summarization module 124, may be capable of crawling text within shared content of an application and summarizing the discovered confidential content, for example by replacing it with the appropriate words, such as “Name”; “Private bank information”; “Private SS information”; and so forth.

In alternative embodiments, data summarization module 124 may be capable of blurring, removing, or covering up confidential content discovered by natural language processing techniques.

In alternative embodiments, data summarization module 124 may expand a summarized content to full content during a screen share with second computing device 130, and revert the full content back to the summarized content upon detecting a user is away from the second computing device 130. For example, data summarization module 124 may be capable of detecting idle time of computing device 130 and if a certain threshold of idle time is reached, the full content share may revert back to the summarized content, thus avoiding potentially sensitive content from remaining open on a computer screen of second computing device 130 when a user may have walked away from the computer.

In another alternative embodiment, data summarization module 124 may require a user of second computing device 130 to re-enter a password if a certain threshold of idle time has elapsed without any keyboard strokes. In yet another alternative embodiment, data summarization module 124 may end a screen sharing session altogether if determined that the second computing device 130 is idle for a certain threshold of time.

In another alternative embodiment, data summarization module 124 may revert the full content of a screen share back to a summarized content based on second computing device 130 detecting that a user has moved away from the keyboard, via a camera on second computing device 130. Detection of a user moving away from second computing device 130 may also be determined by picking up a change in the lighting of a room, via the computer camera or light sensors on second computing device 130, which may indicate that a user has left the room.

With continued reference to FIGS. 1 and 2, information delivery module 126 includes a set of programming instructions in screen sharing protection program 120. The set of programming instructions is executable by a processor. Information delivery module 126 transmits, by the first computing device 110, the summarized content, to be shared by the one or more applications, with the second computing device 130 (step 206).

In exemplary embodiments, information delivery module 126 may determine whether it is acceptable to share the summarized content based on a user at second computing device 130 indicating that it is acceptable to share. Based on the user at second computing device 130 indicating it is acceptable to proceed with a screen share, information delivery module 126 may transmit the summarized content to be shared by the one or more applications. For example, information delivery module 126 may pop up an avatar on second computing device 130 to ask the receiver if it is OK to share the screen at the current time. This safety measure may prevent an unwanted screen share, or private message, when there may be other people around or if the user is engaged in a different screen share with other user(s).

In an exemplary embodiment, information delivery module 126 may replace the summarized content with a code name when the second computing device 130 is engaged in a different screen sharing session at the time of receiving the summarized content, wherein the code name is based on a communication history between the first computing device 110 and the second computing device 130. A code name may include a word, a sentence, or a phrase that may refer to a specific document, conversation, topic, etc. that the user of the second computing device 130 may recognize. For example, a user on second computing device 130 may receive an instant message from a user on first computing device 110 referencing a prior confidential instant messaging conversation from earlier that day. A code name (e.g. “Earlier conversation” or “Business project”) may convey the topic of the conversation, or a reference to the prior conversation, without revealing any confidential information that may accidentally be seen by a third party in the event the user on second computing device 130 is currently engaged in a screen sharing session with a third party. This safety mechanism prevents the accidental, or incidental, revelation of confidential information to one or more third-parties. When the second computing device 130 is dis-engaged from the third-party screen sharing session, the receiver may then access the information containing the code name.

The network may comprise copper transmission cables, optical transmission fibers, wireless transmission, routers, firewalls, switches, gateway computers and/or edge servers. A network adapter card or network interface in each computing/processing device receives computer readable program instructions from the network and forwards the computer readable program instructions for storage in a computer readable storage medium within the respective computing/processing device.

Computer readable program instructions for carrying out operations of the present invention may be assembler instructions, instruction-set-architecture (ISA) instructions, machine instructions, machine dependent instructions, microcode, firmware instructions, state-setting data, or either source code or object code written in any combination of one or more programming languages, including an object oriented programming language such as Smalltalk, C++ or the like, and conventional procedural programming languages, such as the “C” programming language or similar programming languages. The computer readable program instructions may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider). In some embodiments, electronic circuitry including, for example, programmable logic circuitry, field-programmable gate arrays (FPGA), or programmable logic arrays (PLA) may execute the computer readable program instructions by utilizing state information of the computer readable program instructions to personalize the electronic circuitry, in order to perform aspects of the present invention.

Aspects of the present invention are described herein with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the invention. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer readable program instructions.

These computer readable program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. These computer readable program instructions may also be stored in a computer readable storage medium that can direct a computer, a programmable data processing apparatus, and/or other devices to function in a particular manner, such that the computer readable storage medium having instructions stored therein comprises an article of manufacture including instructions which implement aspects of the function/act specified in the flowchart and/or block diagram block or blocks.

The computer readable program instructions may also be loaded onto a computer, other programmable data processing apparatus, or other device to cause a series of operational steps to be performed on the computer, other programmable apparatus or other device to produce a computer implemented process, such that the instructions which execute on the computer, other programmable apparatus, or other device implement the functions/acts specified in the flowchart and/or block diagram block or blocks.

The flowchart and block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods, and computer program products according to various embodiments of the present invention. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of instructions, which comprises one or more executable instructions for implementing the specified logical function(s). In some alternative implementations, the functions noted in the block may occur out of the order noted in the Figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts or carry out combinations of special purpose hardware and computer instructions.
